PORTABLE BED LAMP Filed April 18, 1936 Patented Feb. 2, 1937 T OFFICE 1 Claim.

This invention relates to improvements in portable bed lamps and is particularly designed for use in hospitals. The lamps now in use in hospitals are far from satisfactory in many respects. They usually have a clamping engagement with some part of the bed and, when applied to the head of the bed, are very apt to disfigure the wall at the back of the bed.

An object of the present invention is to provide a portable bed lamp that may be either held from accidental displacement or instantly removed from its position for use in examining a patient and replaced with equal celerity and facility.

Another object of the invention is to provide a lamp which can be tilted at any desired angle and can also be rotated.

A further object of the invention is the provision of holding means for the lamp structure which will not mar the Wall at the rear of the bed, as is usually the case when the present types of attachments are used.

With these objects in View, the invention is described in the following specification, its salient features are pointed out in the claim and it is illustrated by the accompanying drawing, in which:

Figure 1 is a vertical section through the crossbar of a bed frame.

Figure 2 is a section through sleeve showing the lamp in position.

Figure 3 is a section and plan showing groove and slot in sleeve.

Figure 4 is a View showing a modified type of sleeve.

Figure 5 is a view showing a further modification of sleeve structure.

By referring to Figure 1 of the accompanying drawing, it will be noted that the top cross-bar l of a metal bed is provided with a vertical bore into which a sleeve 2 is inserted and firmly held in place by flanging its bottom against the under face of the cross-bar and welding, or otherwise fixing it thereto. As illustrated by Figure 3, the inner face of this sleeve is formed with an annular groove 3 adjacent its top that communicates with a slot 4 at the top of the sleeve. The slot and groove are provided for the reception of a pin 5, Figure 2, which projects from the shaft 6 which is attached to the lower U-shaped portion 8 of the hinge member 1, the upper portion 9 of which is connected with the metal tube l6, Figure 1, which runs from the lamp socket l2 and contains the cord l3 to the free end of which a plug, not shown, is attached for connection with a source of electricity. The handle I! that covers the tube i is preferably made of Bakelite. The sleeve 2 is so mounted that the slot will be toward the left side of the patient, in order that a physician may easily remove the lamp by turning it so that its front, which carries the pin, will be in line with the slot. The hinge portions are provided with aligned openings that receive a rivet it, Figure 2, which is encompassed by a spiral spring is. This spring acts to provide frictional engagement between these portions for the purpose of holding them in adjusted positions. It is obvious that the light from the lamp can be directed as desired. The shade, as shown in Figure 1, is swiveled so that it can be rotated, while the parts of the hinge structure l, Figure 2 are relatively swingable. The shaft 6 is also rotatable Within the sleeve.

In the modification illustrated by Figure 4, the shaft 6 is cut to provide a pair of complementary resilient legs IE and ll that are curved at their free ends 98. The curved portions project from the lower end of the sleeve and rotatably and removably keep the shaft in place.

The modification shown by Fig. includes a resilient, cone-shaped member l9 that is carried by the inner face of the sleeve 2. This resilient member receives the shaft 6 and rotatably and removably keeps it in place by engaging the tapered end of the shaft immediately above its cylindrical portion 20. The top of this cylindrical portion is beveled, as at 2!, to facilitate the removal of the shaft from the sleeve.

This device, once installed, will not mar nor deface the enamel or painted finish of the bed by being moved from one position to another and, at the same time, is interchangeable to fit different beds. It eliminates the danger of fire by never being in sufiiciently close contact with bed linen to cause ignition by heat from the electric light bulb, which is a potential danger in most of the bed lights now on the market,--yet its light can be directed to any position desired.

While a preferred form of structure has been illustrated and described, it is obvious that certain changes may be made without departing from the principle of invention. All such changes are covered by the present specification as limited by the claim.

What I claim is:

In a portable bed lamp structure, a grooved and slotted sleeve extending through a vertical bore in the cross-bar of a bed, a shaft formed with a pin that cooperates with said groove and slot to retain or permit the removal of said shaft from said sleeve, and a lamp adjustably and intermediately connected with said shaft.
